OVERVIEW
Additel’s new Multi-functional Documenting Process Calibrator series takes portability, functionality, and accuracy to
a whole new level and packages it with an intuitive and easy to use color touchscreen display. This series includes an
advanced documenting pressure calibrator (ADT227) and an advanced documentation process calibrator with a built-
in HART communicator (ADT227-HART). Additionally, each calibrator has an ATEX certied intrinsically safe option
(ADT227Ex) allowing you to perform calibration in the harshest of environments. We’re condent these new tools will not
only meet your calibration requirements but will make metrology simple for you!
Features
Easy-to-use Cellphone Like Interface
The ADT227 series brings an all new user interface to the world of process
calibrators. With a menu driven interface and a small size/weight, the ADT227
is the industry's smallest advanced multifunctional process calibrator with an
intrinsically safe version to boot (ADT227Ex). It adopts advanced human hand
engineering design for the most convenient eld handheld process calibrator
available.
The ADT227 has been developed with a powerful embedded operating
system which solves common problems of other designs including slow
response, cumbersome key operation, high power consumption and overall
slow processing.

Features
Thermocouple Measurement Performance
The ADT227 series delivers highly improved thermocouple measurement
capabilities by vastly improving the cold junction compensation(CJC)
specications and a much improved stabilization time.
Portable and Robust
The demands of remote calibration work can be challenging. The ADT227series is
lightweight and highly portable and utilizes an advanced color LCD screen to help ensure
you can easily see, even in the (Ex) intrinsically safe versions.
Pressure / Process Calibration Equipment
The Additel 227Ex series calibrators have passed the most stringent testing by
certied organizations to acquire intrinsically safe certicates, ATEX, IECEX, CSA
and UKCA. The explosion-proof grade (Ex ia IIC T4 Ga), can be widely used in
potentially explosive environments, such as oil and gas platforms, oil reneries,
chemical and petrochemical plants, pharmaceutical industries, energy and gas
processing industries.
Each intrinsically safe calibrator has an advance transective color LCD display
which has enhanced visibility when viewed in direct sunlight. No matter where
your work takes you, these calibrators are up to the task.
All models in the ADT227 family have been designed with ruggedness and dependability in
mind and meet IP67 standards with a 1-meter drop test, 4G vibration, xenon exposure and
130g steel ball drop testing of the display.
Other environmental conditions have also been considered, such as temperature and
humidity. To combat these external elements, Additel has designed a unique internal circuit
design and process technology to allow for the utmost condence in your critical calibration
and measurement work.
Intrinsically Safe Option
Voltage Meter (RMS)
The Additel 227 non-Ex version is equipped with “true effective
value” RMS measuring function, which can measure the RMS
of various waveforms with no need to consider distortion or
waveform parameters and other errors caused by various
waveforms
02
Automated Tasks for Paperless Calibration Management
Additel 227 Series Calibrators come with a powerful documenting calibration task
application which provides a turnkey solution for automation and paperless calibration
management.
Tasks are easily created for temperature, pressure, ow and loop instruments. Up
to 10,000 documented tasks for ADT227 and up to 1,000 documented tasks for
ADT227Ex can be stored in the extensive on-board memory. Many tasks, when
executed, are fully automated in data collection and performance validation, such as
pass/fail and hysteresis calculations. All information can be integrated into Additel’s
ACal software for additional calibration management.
Full HART Communicaton ( For ADT227-HART only)
The built-in full HART communicator will work with most HART transmitters . The
ADT227-HART contains an extensive DD library to meet the needs of your smart
transmitter. Our DD library is updated on a regular basis and at no additional cost.
The ADT227Ex-HART is integrated with the HART communication functions,
permitting users to monitor, control, and calibrate HART instrumentations.
It's an ideal device for calibrating, maintaining, and troubleshooting HART
instrumentations

Features
Targeted application features
The onboard applications provide a useful selection of features including HART communicator,
high static differential pressure mode, pressure leak test, safety valve test, analog transmitter
calibration, unit converter, thermal calculator, and snapshots to name a few.
High static differential pressure mode uses two sensors, unique calculation technology to
achieve a differential pressure measurement to 0.002% FS at high static pressures. The leak
test will automatically calculate the pressure drop to determine a leak condition. The safety
valve test is a specialized task which captures the exact pressure release point by taking 10
readings per second during a valve crack test.
Pressure / Process Calibration Equipment
The ADT227 calibrator can record pressure, temperature and electrical signals.
Recorded values can be displayed numerically or graphically to identify trending. The
ADT227 & ADT227-HART can store up to 500 results. each result can include up to
100,0000 recordings and each recording can record a maximum of 7 channel values.
These results can easily be exported to Additel’s application software. Each log
session is easily congured at a set interval and provides a date and time stamp with
each reading.
In addition to all the great features mentioned above, the ADT227series is loaded
with time saving features like our builtin pressure and temperature converter, thermal
calculator, wiring diagram guide for assisting with electrical connections, a built-in
diagnostic center including intelligent alarm messaging and a real time error report
and comprehensive selftesting to help our customers get the very most out of their
investment in Additel calibration tools.
You will nd this and much more as we continue to develop new apps at Additel.
Data Logger
( For ADT227 & ADT227-HART only)
Connectivity & Battery
Users can remotely connect mobile devices to the ADT227 via Bluetooth with
an unobstructed distance up 20 meters. The included USB type-C comm port
and cable provide a hard wired communication option as well as charging for the
removeable Li-ion battery, which provides up to 35 hours of run time.
